Hochfrequenz-ComputermausHigh frequency computer mouse

Die Erfindung betrifft eine Hochfrequenz-Computermaus, insbesondere eine Hochfrequenz-Computermaus, welche einen einfachen Hochfrequenz-Senderschaltkreis verwendet, wodurch ein Kalibrier-Schritt nicht erforderlich ist und die Herstellung vereinfacht und die Produktausbeute verbessert ist.The invention relates to a high frequency computer mouse, in particular to a high frequency computer mouse which uses a simple high frequency transmitter circuit, thereby eliminating the need for a calibration step and simplifying manufacturing and improving product yield.

Die herkömmliche Computermaus ist normalerweise über eine Anschlußleitung mit dem Computer verbunden. Aufgrund der begrenzten Länge der Anschlußleitung kann das Verwenden der Maus unbequem sein.The traditional computer mouse is usually connected to the computer via a connecting cable. Due to the limited length of the connecting cable, using the mouse can be inconvenient.

Für einen drahtlosen Betrieb wurde eine Infrarot-Computer-Maus entwickelt. Da die Infrarot-Computer-Maus jedoch eine gerichtete Vorrichtung darstellt, kann sie bezüglich dem Computer nicht in einer willkürlichen Ausrichtung angeordnet sein.An infrared computer mouse was developed for wireless operation. However, since the infrared computer mouse is a directional device, it cannot be positioned in an arbitrary orientation with respect to the computer.

0 Um das obige Problem zu vermeiden, wurde die Hochfrequenz-Computertastatur entwickelt, welche drahtlosen und ungerichteten Betrieb ermöglicht. Jedoch ist die Hochfrequenz-Tastatur teuer und weist einen komplizierten Schaltkreisaufbau auf, wodurch potentielle Käufer abgeschreckt werden.0 To avoid the above problem, the high frequency computer keyboard was developed, which enables wireless and omnidirectional operation. However, the high frequency keyboard is expensive and has a complicated circuit structure, which deters potential buyers.

Es ist ein Ziel der Erfindung, eine wirtschaflieh attraktive drahtlose Computermaus zu schaffen, welche geringe Herstellungskosten sowie hohe Stabilität und große Produktionsausbeute aufweist.It is an object of the invention to provide an economically attractive wireless computer mouse which has low manufacturing costs as well as high stability and high production yield.

Dieses Ziel wird erreicht durch eine Vorrichtung mit den Merkmalen nach den Ansprüchen 1 bzw. 3. Bevorzugte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen beansprucht.This object is achieved by a device having the features according to claims 1 and 3, respectively. Preferred embodiments of the invention are claimed in the dependent claims.

Die Erfindung wird unter Bezugnahme auf die Zeichnungen näher erläutert. In der Zeichnung zeigen:The invention is explained in more detail with reference to the drawings. In the drawing:

Wie aus Fig. 1 und 2 ersichtlich, weist die Hochfrequenz-Computermaus nach der ersten bevorzugten Ausführungsform der Erfindung eine Rollkugelvorrichtung (tracking ball means) und einen Hochfrequenz-Sender 1 auf. Der Hochfrequenz-Sender 1 5 verwendet ASK-Modulation und weist einen Transistor Ql, einen LC-Hochfrequenz-Dämpfungsschaltkreis 11, einen Emitterwiderstand R3, ein Oberflächenwellenbauelement (SAW) 12 und eine LC-Schaltkreiskomponente 13 auf.As shown in Figs. 1 and 2, the high frequency computer mouse according to the first preferred embodiment of the invention comprises a tracking ball means and a high frequency transmitter 1. The high frequency transmitter 15 uses ASK modulation and comprises a transistor Q1, an LC high frequency attenuation circuit 11, an emitter resistor R3, a surface acoustic wave (SAW) device 12 and an LC circuit component 13.

0 Insbesondere ist die Basis des Transistors Ql an das Oberflächenwellenbauelement 12 angeschlossen und über einen strombegrenzenden Widerstand Rl und einen Kondensator C3 an ein Steuer-IC 2 angeschlossen, welches einen Mikroprozessor Ul, Widerstände RIO, RIl, Kondensatoren C7, C9 bis CIl und einen Kristalloszillator Yl aufweist. Der Eingang des Steuer-IC 2 ist an die Rollkugelvorrichtung 3 angeschlossen.0 In particular, the base of the transistor Ql is connected to the surface acoustic wave device 12 and is connected via a current-limiting resistor Rl and a capacitor C3 to a control IC 2 which has a microprocessor Ul, resistors RIO, RIl, capacitors C7, C9 to CIl and a crystal oscillator Yl. The input of the control IC 2 is connected to the trackball device 3.

Der Kollektor des Transistors Ql ist an die Spannungsquelle Vcc The collector of the transistor Ql is connected to the voltage source V cc

über den LC-Hochfrequenz-Dämpfungsschaltkreis 11 angeschlossen und die Kollektorspannung wird über den LC-Schaltkreis 13, welcher eine Spule L2 und einen Kondensator C8 aufweist, der Antenne ANT zugeführt.
5via the LC high frequency attenuation circuit 11 and the collector voltage is supplied to the antenna ANT via the LC circuit 13, which has a coil L2 and a capacitor C8.

Der Emitter des Transistors Ql ist über einen Emitterwiderstand R3, welcher die Größe des Stroms festlegt, der durch den Oszillator fließt und die Leistung des Sendesignals bestimmt, an Masse angeschlossen.The emitter of transistor Ql is connected to ground via an emitter resistor R3, which determines the magnitude of the current flowing through the oscillator and determines the power of the transmitted signal.

Die Vorspannung des Transistors Ql wird durch den Ausgang des Steuer-IC 2 gesteuert. Wenn der Ausgang des Steuer-IC 2 einen "High"-Pegel aufweist, ist der Transistor Ql eingeschaltet und sendet ein Signal der durch das Oberflächenwellenbauelement erzeugten Trägerfrequenz. Ansonsten ist der Transistor Ql ausgeschaltet und kein Signal wird erzeugt.The bias voltage of the transistor Ql is controlled by the output of the control IC 2. When the output of the control IC 2 has a "high" level, the transistor Ql is turned on and sends a signal of the carrier frequency generated by the surface acoustic wave device. Otherwise, the transistor Ql is turned off and no signal is generated.

Der Sender 1 verwendet das Oberflächenwellenbauelement 12 als Schwingquelle und sendet das Ausgangssignal des Steuer-IC 2 0 mittels des Transistors Ql aus.The transmitter 1 uses the surface acoustic wave device 12 as an oscillation source and transmits the output signal of the control IC 20 via the transistor Q1.

Aus Fig. 3 und 4 ist das Schaltbild der zweiten bevorzugten Ausführungsform der Erfindung ersichtlich. Wie aus den Figuren ersichtlich, verwendet der Hochfrequenz-Sender 1 ebenfalls LC-Oszillation und ASK-Modulation. Die Oszillation wird mittels des Abstimm-Oszillator-Schwingkreises erzeugt, welcher eine Spule L2, Kondensatoren C5, C6 und C14 aufweist, wobei die Spule L2 eine bogenförmige Kupferspule ist, welche auf einer Platine ausgebildet ist, um eine einstellbare und sehr kleine 0 Induktivität vorzusehen. Der Kondensator C14 ist ein verstellbarer Kondensator von sehr geringer Kapazität, wobei die Frequenz des gesendeten Signals durch Verstellen der Kapazität des Kondensators C14 einstellbar ist.3 and 4 show the circuit diagram of the second preferred embodiment of the invention. As can be seen from the figures, the high frequency transmitter 1 also uses LC oscillation and ASK modulation. The oscillation is generated by means of the tuned oscillator circuit which comprises a coil L2, capacitors C5, C6 and C14, the coil L2 being an arc-shaped copper coil formed on a circuit board to provide an adjustable and very small 0 inductance. The capacitor C14 is an adjustable capacitor of very low capacitance, the frequency of the transmitted signal being adjustable by adjusting the capacitance of the capacitor C14.
